The 3G Stepper from 3G Bikes is a bicycle that is powered by your vertical motion. Instead of peddling with your two feet like a normal human being, you stand upright and place your feet on two decks on either side of the bicycle. Movement here is what powers the bicycle. If this catches on, I don't see why we don't return to those old timey bikes with a huge wheel in the front and a tiny one in the back since they're both as silly looking. Jump for a few more pics of this fine invention.
